The aircraft started the takeoff roll on runway 33 at Lima (LIM). When reaching VR speed (207 km/h) the copilot announced "rotation" and the captain raised the nose of the airplane. At V2 (242 km/h) it reached a positive climb and the undercarriage was raised. From a height of 5 m the airplane began to descend again. It contacted the runway with the tail and skidded for about 200 meters before coming to rest.
It appears that an overweight takeoff was carried out with flaps at 0 degrees instead of 15 degrees.

Probable Cause:

CONCLUSIONES: "La Comisión de Investigación de Accidentes de Aviación del Ministerio de Transportes y Comunicaciones, determina sobre la(s) probable(s) causa(s) del accidente, como siguen a continuación:
El impacto de la aeronave contra el terreno sin pérdida de control debido al deficiente despacho, planeamiento, ejecución de las Listas de Verificación y CRM de la tripulación permitiendo que se inicie la carrera de despegue y rotación con sobrepeso (25,798kgs) y 0° de flap ya que para un peso de 25,000kgs correspondía 15 ° de flaps de acuerdo al Manual de Vuelo de la aeronave. Así mismo el no abortar el despegue ante el no funcionamiento de la alarma de configuración.
- El sobrepeso de la aeronave, que se debió al deficiente procedimiento empleado por un mismo tripulante que ejerció funciones de despachador y navegante en Lima, al incumplir con lo dispuesto en el MGO de la empresa ATSA.
- Las Listas de Verificación que no se ajustan al orden indicado en el Manual de Vuelo (Anexo 3) del avión."
